Piston closes $15M Series A to run cardless payments across commercial fleets — no card swipe, no card rails. 🎙️

The vertical specificity matters more than the payment innovation. Piston is not building a general payments layer; it is building a closed-loop network where the merchant set (gas stations, convenience stores) and the buyer set (fleet operators) are both captive and repeat. That network effect compounds in ways a horizontal payments product cannot replicate.

Fleet managers do not churn. If Piston owns the fuel transaction, it owns the data to underwrite the next credit product. That is the actual business.

Today's brief also covers Pine Labs CORA automating fraud investigation workflows, Graph AI's $13.3M Series A for patient safety, India's ecommerce dark-pattern amendment, and ARC's ₹10.5Cr pre-seed for a portable gaming console.
